Benign paroxysmal positional vertigo (BPPV) is a disorder arising from a problem in the inner ear. [3] Symptoms are repeated, brief periods of vertigo with movement, characterized by a spinning sensation upon changes in the position of the head. [1] This can occur with turning in bed or changing position. [3]
[3] [5] The use of tympanostomy tubes (ventilation tubes) to improve vertigo and hearing in people with Ménière's disease is not supported by definitive evidence. [5] Ménière's disease was identified in the early 1800s by Prosper Menière. [5] It affects between 0.3 and 1.9 per 1,000 people. [1]
Dizziness affects approximately 20–40% of people at some point in time, while about 7.5–10% have vertigo. [3] About 5% have vertigo in a given year. [10] It becomes more common with age and affects women two to three times more often than men. [10] Vertigo accounts for about 2–3% of emergency department visits in the developed world. [10]
Cochlear hydrops preferentially affects the apex of the cochlea where low-frequency sounds are interpreted. Due to the fluid imbalance in this area, parts of the cochlea are stretched or under more tension than usual, which can lead to distortions of sound, changes in pitch perception, or hearing loss, all usually in the low frequencies.
Among the patients with unclassified or idiopathic vertigo, the prevalence of migraine was shown to be elevated. In another study, migraine patients reported 2.5 times more vertigo and also 2.5 more dizzy spells during headache-free periods than the controls. [5] MAV may occur at any age with a female:male ratio of between 1.5 and 5:1.
An individual may experience BPPV when rolling over to the left or right, upon getting out of bed in the morning, or when looking up for an object on a high shelf. [4] The cause of BPPV is the presence of normal but misplaced calcium crystals called otoconia , which are normally found in the utricle and saccule (the otolith organs) and are used ...

In BPPV, the nystagmus typically occurs in A or B only, and is torsional—the fast phase beating toward the lower ear. Its onset is usually delayed a few seconds, and it lasts 10–20 seconds. As the patient is returned to the upright position, transient nystagmus may occur in the opposite direction.
